Prevalence of work-related musculoskeletal disorders (WRMSDs) among general dental practitioners and orthodontists is approximated to range between 64% and 93%. Etiology of WRMSDs in the mentally and physically demanding occupation remains unclear, for which reason the aim of the study was to clarify the interplay of physical, psychological, and mental factors on WRMSDs.
Of 94 orthodontists and 187 general dental practitioners (mean age = 35 years) questioned using an online survey, 84% reported persisting tension or pain in the back, neck, or shoulders. While 71% of females were employed (29% self-employed), only 39% of male participants were employed. Cluster analysis was used to characterize dental practitioners according to their movement profile and the moderating effect of stress on certain WRMSDs.
Three movement profiles of general dental practitioners and orthodontists were significantly predictive of WRMSD. The minority could be characterized as healthy (n = 45), whereas twice as many reported nearly twice as much pain (n = 90). Stress proved to be a strong, significant moderator of WRMSDs in relation to sex, employment status, and body mass index.
The prevalence of WRMSDs found was alarming. Given the feminization of dentistry, and that being female, stressed, and an employee (rather than self-employed) is a significant predictor of WRMSDs, this represents a danger to the German health system.
普通牙科医生和正畸医生与工作相关的肌肉骨骼疾病（WRMSD）的患病率估计在 64%至 93%之间。由于精神和身体要求高的职业中 WRMSD 的病因仍不清楚，因此本研究的目的是阐明身体、心理和精神因素对 WRMSD 的相互作用。
通过在线调查询问了 94 名正畸医生和 187 名普通牙科医生（平均年龄=35 岁），其中 84%报告背部、颈部或肩部持续紧张或疼痛。虽然 71%的女性受雇（29%为自雇），但只有 39%的男性参与者受雇。聚类分析用于根据牙科医生的运动特征和压力对某些 WRMSD 的调节作用来描述牙科医生。
普通牙科医生和正畸医生的三种运动特征可显著预测 WRMSD。少数人可以被描述为健康（n=45），而报告疼痛的人数几乎是其两倍（n=90）。压力被证明是 WRMSD 的一个强有力的、显著的调节因素，与性别、就业状况和体重指数有关。
发现的 WRMSD 患病率令人震惊。考虑到牙科的女性化，以及女性、压力大和受雇（而非自雇）是 WRMSD 的重要预测因素，这对德国卫生系统构成了威胁。
